Example
The example of the brown garden snail (Cornu aspersum) finely demonstrates, how the scientific name of a snail species has developed over the centuries, what the procedures are in providing scientific names (or what they are not), and that sometimes there are special cases. The story begins with the Danish naturalist Otto Friedrich Müller (1730-1784). In 1774, he published his book "Vermium Terrestrium et Fluviatilium seu animalium infusorium, helminthicorum, et testaceorum non marinorum succincta historia", first mentioning Helix aspersa, literally the spotted snail, because at that time, at least all round snails were called Helix.
